Spurweed (Lawn Burweed) Control: Timing Is Everything

Spurweed (Soliva pterosperma) germinates in fall, grows silently through winter, and produces painful burs by Easter. Two effective windows:

1. September: Apply broadleaf pre-emergent.
2. Early March: Spot-spray young rosettes with broadleaf post-emergent (2–3 applications, 2 weeks apart).

Prevent seed set for two consecutive springs and the seed bank depletes. Don’t confuse with grassy sandspur (Cenchrus), a coastal problem.
